100/// Pyright assigns each completion item a `sortText` of the form `XX.YYYY.name`.
101/// Where `XX` is the sorting category, `YYYY` is based on most recent usage,
102/// and `name` is the symbol name itself.
103///
104/// The problem with it is that Pyright adjusts the sort text based on previous resolutions (items for which we've issued `completion/resolve` call have their sortText adjusted),
105/// which - long story short - makes completion items list non-stable. Pyright probably relies on VSCode's implementation detail.
106/// see https://github.com/microsoft/pyright/blob/95ef4e103b9b2f129c9320427e51b73ea7cf78bd/packages/pyright-internal/src/languageService/completionProvider.ts#LL2873
